Common Home Inspection Issues and How to Fix Them

When you buy a home, you want to feel confident that it is safe, strong, and ready to live in. That is why a home inspection is one of the most important parts of the buying process. A professional inspector can find problems that you may not notice on your own. Many of these issues are common in homes across the USA, and the good news is that most of them can be repaired with the right steps.

In this guide, we will look at the most common home inspection issues and share simple ways to fix them. Whether you are a homebuyer or a homeowner preparing to sell, this information will help you understand what to expect and how to keep your home in great shape.

1. Roof Problems

One of the most common issues found during a home inspection is roof damage. Roofs naturally wear down over time from wind, rain, snow, and sun exposure.

Common Signs of Roof Problems

• Missing or curled shingles
  
  
• Leaks or water stains on ceilings
  
  
• Damaged flashing around chimneys and vents
  
  
• Sagging areas
  
  

How to Fix It

The best solution depends on the level of damage:

• Replace missing shingles: A roofer can match the material and repair small areas.
  
  
• Fix flashing: Tighten or replace metal flashing to stop leaks around chimneys and pipes.
  
  
• Full roof replacement: If the roof is very old or has major damage, replacing it may be the safest option.
  
  

2. Electrical Issues

Electrical problems can be dangerous, so inspectors always check the system carefully. Old homes often have outdated wiring that may not meet modern safety standards.

Common Electrical Problems

• Exposed wires
  
  
• Overloaded circuits
  
  
• Non-working outlets
  
  
• Old electrical panels
  
  

How to Fix It

Electrical repairs should always be done by a licensed electrician.

Fixes may include:

• Replacing damaged wires
  
  
• Updating the panel
  
  
• Adding more circuits
  
  
• Installing GFCI outlets in kitchens, bathrooms, and outdoor areas
  
  

These improvements help protect your home from electrical fires and reduce the risk of shocks.

3. Plumbing Leaks and Water Damage

Water damage is one of the most expensive issues if not caught early. Inspectors often find leaks under sinks, in bathrooms, around water heaters, and in basements.

Common Plumbing Problems

• Dripping faucets
  
  
• Leaky pipes
  
  
• Slow drains
  
  
• Water heater corrosion
  
  

How to Fix It

• Repair or replace damaged pipes: PVC or copper piping is often used as a modern fix.
  
  
• Clear clogged drains: Drain cleaning tools or professional plumbers can help.
  
  
• Replace old water heaters: If the tank is rusted or leaking, it's time for a new unit.
  
  

If you see any signs of mold, make sure to remove it and fix the moisture source to prevent it from coming back.

4. Foundation Cracks

Foundations can crack as the soil moves or settles. Some cracks are small and normal, while others can be a sign of bigger issues.

Common Signs of Foundation Problems

• Visible cracks in walls or floors
  
  
• Doors or windows that don’t close properly
  
  
• Uneven floors
  
  

How to Fix It

The right fix depends on the size of the crack:

• Small cracks: These can be sealed with epoxy or polyurethane filler.
  
  
• Larger cracks or sinking: A foundation specialist may need to use piers or jacks to lift and stabilize the home.
  
  

Foundation repairs can be costly, but catching issues early makes them far easier to fix.

5. HVAC Problems

Heating and cooling systems need regular maintenance. During inspections, many HVAC issues come from lack of cleaning or old equipment.

Common HVAC Issues

• Dirty filters
  
  
• Poor airflow
  
  
• Old or failing furnace units
  
  
• Leaks in ductwork
  
  

How to Fix It

• Replace filters every 1–3 months
  
  
• Clean vents and ducts
  
  
• Schedule yearly HVAC inspections
  
  
• Replace outdated units for better performance and efficiency
  
  

A well-maintained HVAC system keeps your home comfortable and helps lower energy costs.

6. Poor Drainage and Grading

Water should always flow away from your home. If the yard slopes toward the house, water can build up around the foundation and cause damage.

Common Drainage Problems

• Pooling water around the home
  
  
• Damp basements
  
  
• Soil erosion
  
  
• Standing water near gutters
  
  

How to Fix It

• Regrade the soil so it slopes away from the house
  
  
• Extend downspouts to move water farther out
  
  
• Clean gutters to improve flow
  
  
• Add French drains in areas where water collects
  
  

Proper drainage protects your home from water damage and mold.

7. Mold and Mildew

Mold grows in damp, dark areas. It is often found in bathrooms, crawl spaces, basements, and around leaks.

Common Signs of Mold

• Musty smell
  
  
• Black, green, or white spots on walls
  
  
• Condensation on windows
  
  
• Allergy-like symptoms
  
  

How to Fix It

• Clean small areas with mold remover
  
  
• Fix moisture problems like leaks or poor ventilation
  
  
• Use dehumidifiers in damp areas
  
  
• Call a mold remediation company for large or toxic mold growth
  
  

Stopping moisture is the key to preventing mold from returning.

8. Insulation and Ventilation Problems

Poor insulation can cause high energy bills and make your home uncomfortable. Many older homes do not have enough insulation in attics, walls, or crawl spaces.

Common Insulation Issues

• Drafts
  
  
• Uneven temperatures
  
  
• Ice dams on roofs
  
  
• High heating or cooling bills
  
  

How to Fix It

• Add insulation in attics and crawl spaces
  
  
• Seal gaps around doors, windows, and pipes
  
  
• Improve ventilation to reduce moisture
  
  

Good insulation helps keep heat in during winter and out during summer.

9. Pest Damage

Termites, rodents, and insects can cause major damage if they are inside a home.

Common Signs of Pest Problems

• Droppings
  
  
• Chewed wires or wood
  
  
• Hollow-sounding beams
  
  
• Small holes in walls
  
  

How to Fix It

• Hire a pest control company to remove the pests
  
  
• Repair damaged wood or wiring
  
  
• Seal entry points around windows, vents, and the roof
  
  

Regular pest inspections can help you avoid expensive repairs later.

10. Safety Issues

Inspectors also check for safety concerns that can put your family at risk.

Common Safety Problems

• Missing smoke detectors
  
  
• Missing carbon monoxide detectors
  
  
• Loose stair railings
  
  
• Trip hazards
  
  
• Unsafe decks
  
  

How to Fix It

• Install smoke and CO detectors on each floor
  
  
• Tighten or replace railings
  
  
• Repair loose boards or uneven steps
  
  
• Replace damaged deck planks
  
  

These simple fixes help keep everyone safe.
